[LeetCode] 673. Number of Longest Increasing Subsequence Given an integer arraynums, returnthe number of longest increasing subsequences. Example 1: Input: nums = [1,3,5,4,7] Output: 2 Explanation: The two longest increasing subsequences are [1, 3, 4, 7] and [1, 3, 5, 7]. Example...
Input: [2,2,2,2,2] Output: 5 Explanation: The length of longest continuous increasing subsequence is 1, and there are 5 subsequences' length is 1, so output 5. 分析: 求出最长递增子序列的个数,我们使用lens[i]表示以nums[i]为结尾的递增子序列中元素的个数也就是长度,以time[i]表示以nums...
Can you solve this real interview question? Number of Longest Increasing Subsequence - Given an integer array nums, return the number of longest increasing subsequences. Notice that the sequence has to be strictly increasing. Example 1: Input: num
Explanation: The length of longest continuous increasing subsequence is 1, and there are 5 subsequences' length is 1, so output 5. Note: Length of the given array will be not exceed 2000 and the answer is guaranteed to be fit in 32-bit signed int. 题目链接:https://leetcode.com/problems...
leetcode 673. Number of Longest Increasing Subsequence Given an unsorted array of integers, find the number of longest increasing subsequence. Example 1: AI检测代码解析 Input: [1,3,5,4,7] Output: 2 Explanation: The two longest increasing subsequence are [1, 3, 4, 7] and [1, 3, 5, ...
673. Number of Longest Increasing Subsequence 问题传送门 问题分析 这个就是动态规划的典型问题,我们假设 lgst(i)表示以nums[i]结尾的递增序列的最大长度。 lgst_num(i)表示nums[i]结尾的最大递增序列的数量。 那么我们就能得出如下递推公式: logs(i) = max(logs(i - 1) + 1, logs(i - 1) + ...
